Abstract Manual assembly is an important link in the aircraft assembly process. However, due to the variety of assembly parts, complex assembly locations, and numerous assembly processes, the assembly efficiency is low and the assembly quality is difficult to guarantee, which severely affects the quality and efficiency of the overall aircraft assembly. Based on the analysis of tracking registration technology and projector-camera calibration technology in spatial augmented reality auxiliary assembly applications, and on the basis of 3D machine vision technology research, this paper develops a full-process projection-guided auxiliary assembly system with functions of projection information edit, workpiece positioning and guidance information projection. By projecting auxiliary assembly information on the surface of aircraft workpieces, the system can simplify complex assembly processes. It can be seen from the verification experiment that the use of this system can significantly improve the assembly efficiency and assembly quality, and greatly shorten the assembly cycle.
